Abstract

The invention relates to a drive, particularly a push and pull drive, which has a cylinder with a cylinder inner chamber (Z) and a cylinder axis (F) and a piston movably arranged in the cylinder and to which is fixed a flexible force transfer means (U). For a double-action drive the cylinder inner chamber (Z) or the piston must have a larger cross-sectional surface than the force transfer means (U). In order that, despite this, the cylinder wall can serve as a guidance means for the flexible force transfer means, either the cylinder inner chamber or the force transfer means has a non-circular cross-section, so that on a cross-section there are at least two points (A1 to A3), on which the cylinder inner wall can guide the force transfer means.
